Title: Improved transmittance in metal-dielectric metamaterials using diffraction grating

Abstract

In this Letter, we experimentally demonstrate the possibility to obtain an improved transmittance from metal-dielectric multilayer metamaterials at optical frequencies. In order to achieve this goal, a properly designed one-dimensional silver diffraction grating has been fabricated on top of two different multilayer structures such as Au/Al{sub 2}O{sub 3} and Au/SiO{sub 2}. It has been observed that the improved transmittance at various resonant wavelength bands is possible from the metal-dielectric metamaterials when it is coupled with a properly designed metallic diffraction grating. The obtained results can be expected to find variety of potential applications including high-efficiency solar cells.
